Take eingt minutes to learn tips for using an Intelligent Fully Automatic Vickers Hardness Tester

I. Pre - operation Preparation
1.Equipment Inspection: Carefully examine the appearance of the uVicky - AI Intelligent Fully Automatic Vickers Hardness Tester to ensure that the equipment is free from damage and all components are firmly connected. Check whether the indenter is securely installed and free from wear. If the indenter shows signs of wear or damage, it must be replaced promptly as this can severely affect the accuracy of the measurement results. Meanwhile, confirm whether the display screen, operation buttons, etc. of the hardness tester are functioning properly.
2.Sample Preparation**: Select an appropriate sample according to the test requirements. The test surface of the sample should be flat and smooth. If the surface is rough, it needs to be polished; otherwise, it will lead to significant deviations in the hardness test results. Ensure that the sample is of a suitable size and can be stably placed on the workbench of the hardness tester. Generally, the thickness of the sample should be no less than 10 times the indentation depth to guarantee the validity of the test results. Additionally, if there are impurities such as oil stains or oxide layers on the sample surface, clean it with an appropriate cleaning agent and then dry it with a clean cloth.
3.Environmental Requirements**: Place the hardness tester on a stable and vibration - free workbench. The surrounding environment should be clean and dry, avoiding direct sunlight and strong electromagnetic field interference. The temperature should be controlled between 10°C - 35°C, and the relative humidity should not exceed 80%, as environmental factors may affect the measurement accuracy of the hardness tester.
II. Parameter Setting
1.Power - on: Connect the power supply of the uVicky - AI Intelligent Fully Automatic Vickers Hardness Tester and wait for the equipment to complete self - check and initialization. At this time, the display screen will show relevant information and the operation interface of the equipment.
2.Test Parameter Setting: Set various test parameters on the display screen according to actual needs. First, select the hardness scale for testing. Commonly used Vickers hardness scales include HV0.05, HV0.1, HV0.2, HV0.3, HV0.5, HV1, HV2, HV3, HV5, HV10, etc. A reasonable choice should be made based on the material and hardness range of the sample. Then, set the test force holding time, which is generally 10 - 15 seconds. However, for some special materials, it can be adjusted appropriately according to standards or experience. In addition, the position coordinates of the test points need to be set. If in the automatic test mode, the coordinates of multiple test points can be set, and the hardness tester will automatically conduct tests according to the preset path.
3.Equipment Calibration: To ensure the accuracy of the measurement results, before formal testing, calibrate the hardness tester using a standard hardness block. Place the standard hardness block on the workbench and perform the calibration operation according to the operation procedure. The hardness tester will automatically calculate and adjust the measurement error.
III. Test Operation
1.Sample Placement: Place the prepared sample steadily on the workbench of the hardness tester. Use the adjustment knobs of the workbench to adjust the sample to an appropriate position so that the test point is directly below the indenter. For samples with irregular shapes, appropriate fixtures may be required to fix them to prevent the sample from moving during the test.
2.Test Initiation: After confirming that all parameters are set correctly and the sample is properly placed, click the "Start Test" button on the display screen. The hardness tester will automatically apply the test force, press the indenter into the sample surface, hold for the set time, and then automatically unload the test force. During this process, the operator should keep observing to ensure the normal progress of the test.
3.Indentation Measurement: After the test is completed, the optical system of the hardness tester will automatically collect the indentation image and accurately measure the diagonal length of the indentation through the built - in AI algorithm. According to the Vickers hardness calculation formula, the hardness tester will automatically calculate the Vickers hardness value of the sample and display it on the display screen.
IV. Data Processing and Recording
1.Data Viewing and Analysis: View the hardness value obtained from the test on the display screen. At the same time, the test report automatically generated by the hardness tester can be viewed, which may contain detailed information such as test time, test point location, and hardness value. If it is necessary to analyze the data of multiple test points, the data processing functions built into the hardness tester can be used, such as calculating the average value, standard deviation, etc.
2.Data Storage and Export: The uVicky - AI Intelligent Fully Automatic Vickers Hardness Tester usually has a data storage function, and the test data can be stored in the device's memory. For the convenience of subsequent data management and use, the data can also be exported to an external storage device, such as a USB flash drive. The exported data is generally in a common document format, such as an Excel spreadsheet, which is convenient for further processing and analysis in other software.
3.Recording and Reporting: Record important test data in paper or electronic documents, including sample information, test parameters, hardness values, etc. According to actual needs, prepare a detailed test report, which may include test purpose, test method, test results, and conclusions, providing a basis for related research, production, or quality control.
V. End - work Procedures
1.Equipment Shutdown: After all test work is completed, click the "Shutdown" button on the display screen to turn off the power of the hardness tester. Before turning off the power, ensure that the data has been saved and exported to avoid data loss.
2. Equipment Cleaning: Remove the sample and wipe the workbench surface with a clean cloth to clean up any possible remaining debris and dust. If there are stains on the indenter or the optical system, use special cleaning agents and tools for cleaning to keep the equipment clean and in good condition.
3. Maintenance and Servicing: Regularly maintain and service the uVicky - AI Intelligent Fully Automatic Vickers Hardness Tester, such as checking whether the mechanical components of the equipment are loose or need lubrication, and calibrating the accuracy of the equipment. Carry out regular maintenance work according to the requirements of the equipment's instruction manual and maintenance manual to extend the service life of the equipment and ensure that it always maintains good performance.
